Demonstration Boards

In combination with AC/DC Power Supply they are intended to be used in grammar schools in order to popularize electronic science as a possible direction of further study. There are four Exercises available, each consists of an appropriate Demonstration board, detailed theoretical instructions on demonstration process and common Power Supply.



Exercise No. 1 - AC-DC difference


Differences between AC (alternating) voltage and DC (direct) voltage. Lamps and loudspeaker are used to present the difference simple, understandable and interesting way.



Exercise No. 2 - Switch connections


Most common connections used on electronic and electric field are presented logic way using a few lamps.



Exercise No. 3 - Ohm's Law


The law will not be boring and easy forgetable if it is presented interesting and practical way. Involved parameters can be followed by instruments (A-meter, V-meter) and various combinations of the parameters can be selected.



Exercise No. 4 - Power and Energy


Involved parameters can be followed by instruments (V-meter, A-meter), power can be practically presented as a resistor heating and light emitting.
